Question

Where is the carbon taken in by plants during photosynthesis stored?
a.
the ground
b.
plant structures
c.
the air
d.
all of the above

Answer 1

b. plant structures

During photosynthesis plants convert CO2 into organic molecules (sugars) and build biomass (leaves, stems, roots). Some of that carbon can later move into soil or back into the air via decomposition and respiration, but immediately after photosynthesis it is stored in plant structures.
